Cedar Playground Chips are perfect for under swings or playground sets. Typically, Cedar Playground Chips are applied at least 6" deep and up to 9" deep under and around playground sets and equipment. On the Consumer Product Safety Commission website, they recommend at least 9" depth. 1 yard of Cedar Chips will cover 54 square feet 6" deep or about 41 square feet 9" deep. Another popular use of Cedar Playground Chips is for dog runs or on pathways to soak up the rain and prevent mud.
